Binders for nonwovens and textiles

Binders are used to improve the mechanical properties of nonwoven and woven textiles, such as dimensional stability, stiffness and tensile strength. Conventional binders are predominantly made of petroleum-based substances (e.g. acrylics), even though the fibers may be entirely from renewable cellulose.

OC-biobinder™ is fiber-binding system based on modified biopolymers and natural plant compounds. It is classified as non-irritating and non-dangerous to the environment by the European REACH regulations, and therefore enables the manufacturing of more sustainable fiber-based materials.

The OC-biobinder™ system can be used on woven textiles to increase stiffness and prevent fraying making it suitable for the manufacturing of sun blinds. On nonwoven or air-laid materials, OC-biobinder™ can increase tensile strength, decrease linting and improve dimensional stability.

The OC-biobinder™ system consists of numerous formulations, affecting the mechanical properties of the fiber-based material in different ways with varying softness, tensile strength, wet stability, etc. The formulations also have different viscosity, solid content, etc. and therefore can be applied to the fiber-based material in different ways. Generally, the fiber-based material is impregnated with an aqueous solution of OC-biobinder™ by dipping or padding. Application by coating and spraying methods are also possible. Subsequent to the application, the fiber-based material is dried at elevated temperatures.

By mimicking nature we now enter a new era within fiber based materials.
Textiles become water repellent. Wood is made durable and fire resistant.
Paper is made stronger and 3D shaped biocomposites can be produced.
All in a sustainable way in harmony with the nature.
